Q: What does CCA mean?

A: CCA stands for Cold Cranking Amps. This is the amount of power exerted by your battery when starting your vehicle on a cold day. The definition by Battery Council International (BCI) is the discharge load in amperes which a new fully charged battery at 0 degrees Fahrenheit can deliver for 30 seconds and maintain a voltage of 1.2 volts per cell or higher. 

B

Q: What is the difference in CCA and CA or HCA? 

A: CA and HCA stands for Cranking Amps and Hot Cranking Amps these ratings are the same as CCA, but are typically tested at 32ºF and 80ºF respectively. These ratings may be useful for people not living in cold weather climates. The 32ºF and 80ºF rating are also sometimes referred to as MCA, or Marine Cranking Amps. 

C 

Q: What does RC or reserve mean? 

A: RC stands for Reserve Capacity . The BCI defines this as the number of minutes which a new, fully charged battery at 80ºF can be continuously discharged at 25 amperes and maintain a voltage equal to or higher than 1.75 volts per cell. This is a useful number should your battery have to provide power for ignition, lighting , etc. in the event of failure in the vehicles electricity generating system. 

D

Q: What is the #1 reason for battery failure? 

A: Positive grid corrosion. This is a natural occurrence over time, however it is accelerated by operating in an extremely hot climate or by overcharging. Overcharging can occur due to malfunction on the part of your vehicle's electrical system. Vibration is also a major reason for battery failure. 

E 

Q: Which is worse for a battery, hot weather or cold weather? 

A: Hot weather. While most of us have grown up thinking that cold weather is the worst weather for a battery, the fact is that your car is simply harder to start on very cold days. This is primarily due to the thickening of the motor oil during extreme cold. Heat actually damages the battery. Studies indicate that the average battery lasts nearly twice as long in a cold weather climate vs. a hot weather climate.

F 

Q: Can a battery freeze? 

A: Yes, if it is in a state of discharge. It is very important to make sure your battery stays fully charged in extreme cold weather. If a battery freezes, it can damage the plates and container. 

G 

Q: Will a battery rapidly self discharge if placed on concrete? 

A: No, placing a battery on concrete will not cause it to discharge any faster than any other surface. 

H 

Q: Can I store a battery indefinitely? 

A: No, a battery will self-discharge slowly over time. Allowing a battery to sit in a discharged state will ultimately lead to severe positive grid corrosion and battery failure. An un-used battery should never be allowed to sit over 6 months without a recharge. 

I 

Q: Do I need to add water or acid  to my battery? 

A: Today's low maintenance and maintenance-free battery's should not require water addition. However, due to a vehicles electrical system sometimes performing at less than 100%, some water addition may be necessary from time to time. It is advised that you periodically check the water level of your battery. If you regenerate a battery you have to test acid capacity and add some if necessary.

J 

Q: What does the battery group size (BCI) refer to? 

A: This refers to the physical dimensions of the battery. It also includes the post type and configuration, hold-down type, etc. 

K 

Q: Can I replace the battery in my vehicle with a different battery group size? 

A: Yes, as long as the voltage is the same (i.e. 12 volts). Before doing this, however, you should make sure that the replacement battery fits in the vehicle and can be properly secured (held down) to avoid excessive vibration. You should also check your vehicle's manual to make certain that you use a replacement battery with sufficient Cold Cranking Amps (CCA). 

L 

Q: Can a battery really explode? 

A: Yes, when working with or near a battery, or jump starting a vehicle, always:
- wear glasses or safety goggles
- shield eyes and face from battery
- keep as much distance as possible from battery
- do not cause any flames or sparks, do not smoke
- read your vehicle instruction manual before jump starting vehicle
- read warning labels on battery
- if you should get acid on your skin or in your eyes, flush with water immediately and seek medical attention

Q: Is the JMF1020 can regenerate batteries from 250 amp/5hours to 1000amp/5hours ?

Let say that the first condition is to have a battery in a good condition. There are two types of battery CA for Cranking Amps and CCA for Cold Cranking amps (see above).  A used 250 amps CCA will take a minimum of 12 hours with a low desulfating charge of maximum 5 amps.  For 1000 amps it will take 24 hours but we are almost sure that you are not using often a 1000 amps battery because it is very unusual

N

Q: Can the batteries of different ampere be connected in series for the regeneration process? Ex. some 12V/40Amp, 12V/60Amp and some of 12V/70Amp

A: Yes there is no problem.  The only battery that should be charge all together is the motorcycle battery of 6 Volts because you can give them more than a  2 amp. charge

O

Q:  Must these batteries be connected in the sequence from smallest ampere to the largest?

A: It is not important.  No sequence is requested

P

Q: Once the connections are done and power switched ON, we turn the knob until the meter shows 4 Amp, but after 2-3 minutes the reading starts to slide to 2-3Amp. What should we do?

A: turn again the knob until you reach the 4-5 amp.  Don't be afraid to break the regenerator or the battery, it is impossible.

Q

Q: The Amp Meter indicates 1-4Amp as CHARGING, and 5-10Amp as DISCHARGING. What does this actually means?

A:  When the needle is below 5 it means that your battery will receive charge.  Normally you should not go over 5 amps but some battery will need  more than 5 amps at the beginning of the regeneration.

R

Q: After 24 hours of regeneration + another 12 hours of cold rest, you mentioned that the battery should have 500Amp. What does this mean and how can we measure to check whether the battery has 500Amp?

A: After 12 hours of rest if you check the battery and she had keep her charge it means that the battery is good.  On your battery tester it will indicate GOOD.

Yes after 24 h of regeneration and 12 h of rest the battery should have between 300 and 500 amps.  You can check that with your battery tester.

S:

Q: If battery being regenerated for 24 hours and left unused on the shelf as stock. How long can this last - 3 months, 5 months or what ?

A: Normally 3 months without any problem

T.

All batteries charged with reading between 5 to 8Amp. Hook-up for 12 hours regeneration. During the starting of the regeneration process, the meter reading slide to 3+Amp. We adjust the knob so that meter reading rise back to 5Amps. After another while, meter again starts to slide back to 3Amp. This continues several times after we adjust back the knob to 4Amp until finally it stays somewhere between 4Amp to 4.5Amp.+
Q1 - Is this normal ?

A: Yes, for the first hours, you have to control the meter amps at 5 amps

Q2 - Are we doing the correct thing by adjusting the knob back to 5 amps every time the meter drops to 3Amp?

A: Yes

U.

After 12 hours, we checked the voltage and ampere reading - and reading is good. But when we start to regenerate for another 12 hours, the same problem arise - meter slide to 3Amp+, and we adjust the knob back until it stays somewhere between 4Amp to 4.5 amps (5 Amps)

Q: Are we doing the correct thing?

A: Yes

V.

After the 24 hours regeneration and another 12 hours rest, we found that the voltage and ampere drops by somewhere 25%. 
Q: Why does this happen?

W

Q Can JMF1020 operates 24 hours continuously every day? 

A:  Yes

X

Q: Do we need to put ventilation fan for the JMF1020? or is it recommended to operate inside air-condition environment? 

A: Not necessary
